SENECIO ERRATICUS. Bertol 



Reported from the Channel Islands and Shropshire, but by 

 mistaking S. aquaticus for this species. 



ASTER. 



Various species of Aster from North America occasionally occur 

 as the outcasts of gardens where they are cultivated, under the 

 name of Michaelmas daisy. Among these I have seen A. brumalis 

 (Nees), A. Novi-belgii (Linn.), and A. leucanthemus (Desf.). 



SOLIDAGO LANCEOLATA. Linn. 



Dr. Walker Arnott states that this North American species is 

 sometimes found "naturalized; " but I have never seen it. 



TUSSILAGO ALPINA. Linn. 



Said by Mr. G. Don to have been found in Eorfarshire ; but it 

 has been found by no one else ; it is the Homogyne alpina of 

 Cassini and most of the continental botanists. 



PICRIS STRICTA. Jord. 



This plant (which appears to be a sub-species of P. hieracioides) 

 was- found in Bantingford, Herts, by the Eev. W. W. Newbould ; 

 but probably it has been introduced with seed from the Continent. 



PRENANTHES PURPUREA. Linn. 



Partially naturalized near the Castle, Isle of Skyc. I have 

 seen it about 1839 on the debris of Salisbury Craigs, Edinburgh, 

 but it was not persistent there. 



CREPIS PULCHRA. Linn. 

 Eng. Bot. No. 2325. 

 Mr. G. Don said that he found this plant among the debris of 

 the rocks of the hills of Turin and Pitsandy, in Porfarshire. Dr. 

 Walker Arnott remarks in the "British Flora," "The very few 

 specimens from Don, which we have seen, are more luxuriant 

 than Smith's acknowledged cultivated one, from which the figure 

 in ' English Botany ' was made."
